Write 0.0000002711 in scientific notation. (Use 2 numbers after the decimal point.)

2.71 x 10^-7

You must have 2 numbers after so it will be 71 after the 2. It’s getting smaller so go to the left. There’s 7 spaces from 2()7 to the new decimal spot

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840
